Mission Objective:

The Saturn-1 booster S-1 stage consisted of a cluster of 8 H-1
engines. One of the appealing features of this configuration was
the added safety of providing for an "engine-out capability" where
other engines could burn longer than planned if an engine cutoff
early. On the SA-4 mission, a premature single engine cutoff
of one engine was programmed 100 seconds into the flight. This
experiment was successful. (NASA SP-4206 page 324).
